About Austin

Learn more about the host city, Austin.

Austin is a city of about 965,000 people (2021) on the southeast edge of the Hill Country region of Texas, making it the fourth-largest city in the state and the 11th-largest in the country. It is the capital of Texas and a college town, and also a center of an alternative culture away from the major cities on the US coasts, though the city is rapidly gentrifying with its rising popularity. Austin's attitude is commonly emblazoned about town on T-shirts and bumper stickers that read: "Keep Austin Weird." Austin is also marketed as the Live Music Capital of the World due to the large number of venues.
